11 Claims.

'I'his invention relates generally to paper or sheet material dispensingdevices, and relates particularly to means for mounting a supply roll ofpaper in a cabinet, and f or facilitating-the connection of the rollwith the mounting means. The invention has for an obfiect to providemeans for preventing wrong placement ofthe roll with reference to adispensing mechanism.

The means for preventing wrong placement of the roll is related to thebroad idea (disclosed in my co-pendlng application 40,794 series of1935) of so feeding paper from a roll; that the tendency of the paper tocurl in a direction toward the roll is utilized forcausing the paper(after delivery through a delivery opening) to assume and 'be maintainedin outwardly spaced relation with respect to the front face of thecabinet so that its end can be easily grasped.

This invention is also related in some respects to the inventiondisclosed in the application of Merle J. West 140,213 series of 1935,now Patent No. 2,146,038 of Feb. 7, 1939, which broadly pro'- videsmeans for preventing such wrong placement .of a roll, as would defeatthe purpose of utilization of the curl'of the paper, for making the samemore accessible for grasping.

'I'he main objects of the present invention are, to provide means forpreventing wrong placement of the roll, and to provide means forfacilitating connection of this last mentioned means. Another object isto providea new means for facilitating the connectionvof the roll withits mount,'independently of any scheme for preventing wrong placement. Ibelieve myself. the first In the West'application 140,213 supra., now

Patent No. 2,146,038 although means are provided for preventing wrongplacement of the roll, the connection of this means might sometimes bedidlcult because of the'requirement of the registration betweenelementsv carried respec tively by the roll and by the mount therefor.The present invention not only provides new forms of connecting meansbetween the roll and the mount. but provides means by which suchconnections are facilitated.

Features ofthe invention include all details of construction shown,along with the broader idea 60 ofproviding guiding means forfacilitating connection of the4 connecting means; f

Objects, features and advantages of the inven- -A tion will be set forthin the description of the 55 in said drawings,

, In the drawings, the device has been shown ous kinds of cabinets.

The cabinet is generally indicated at I. 'It hasa front wall 2 having adelivery opening 3. In this instance the front wall 2 is pivoted as at 4tothe bottom of the cabinet to swing downwardly to a point below thecabinet. The upper edge 5 of the down-swingable front 2 cooperates withthe lower edge 5 of the top of the cabinet to define the down-leadingdelivery opening 3.

Rolls I5 and I6 cooperate to feed the paper. Roll I5f is operated by vacrank 28. A suitable guide 2| directs the paper outwardly and downwardlythrough the opening 3. The paper is guided upwardly and over a tearoknife or blade 25 by which the paper is separated as a result of pullthereon.

It willbe noted that face 21 of the paper which was opposed to the rollfaces, after ejection through the opening 3, is directed toward the userand away from the front 2 of the cabinet. It is noted that paper curlsoutwardly, and thus the natural curl of the paper, due to its originalroll formation, is utilized for facilitating grasping.

Referring now to Figures 2 and 3, a supply roll of paper is indicated at30, and a hollow paper core or tube for the roll is indicated at 3|. Theroll itself may ,be said to provide vaiirially alined openings ordepressions at opposite ends,

but preferably these openings are formed in or by a tubular core or by acore having openings in its ends. Upon this core the paper is woundtightly. This core thus constitutes an element which is permanentlynonrotatably secured in the roll, in a manner to strongly resistdetachment. i

The support or mount for the roll includes an element of sheet metalhaving a horizontal portion 32 and bent up arms 33-34. pivoted as at 35toa plate 35, which plates extend vertically o'f the cabinet and arespaced inwardly from the outer walls 31 of the cabinet. While theparticular mount is claimed in combination it is understood that theinvention is broader than vthe particular structure of the mount.

Referrlng'rst to the form of invention illustrated in Figures 1 to 5inclusive, broadly, means is provided for detachably mounting the roll,including parts which facilitate connection of parts on the roll withparts on the mount.

Referring rst to Figures 3 and 5, a cap-likelelement48isiittedwitl`iinthecoreu soasto close one end thereof.l 'Ihecap may nt' ina depression in a core. Terminal prongs are provided onthe circular inner margin of'this member 4l, the prongs being indicatedat 4|. There are four of these prongs only threeof which are shown.Element 40 is shown asa cup orcap but may be a disc or plate. The use oithis ele-i ment and its immovable attachment in the manner shown is a`feature. As attached it' cannot be removed without considerablediillculty until the supply roll is depleted. `The element is introducedand moved to the position shown in Ill'ig-` ure 3, at which .time theprongs are alined with a cylindrical wall of the cap 4II. After the capvEacharmis.

has been positioned as shown, a tool is introdud into the co're from theopposite end'and the prongs are. forced outwardly to bite into the paperof the core. This is a very eifective and simple means for substantiallynon-removably and non rotatively securing the cap within the core.

The cap 40 has punched-outtherefrom a pair of parallel flat ears orprojections indicated by the numeral 45, and also has punched outtherefrom a pair of arcuate ears or projections 46. 'I'he guide ears 45are alined on a diameter which passes through the rotative axis of theroll. 'Ihe elements and 46 are symmetrically arranged as are thecorresponding elements o-f the mount (see Figure 4), later to bedescribed, to the end that the elements will register forconnecting theparts together and to the end that the guide means can cooperate forfacilitating this connection. While the specific one-piece constructionof its cap and connection and guiding-means is claimed per se, there isno intention to limit the broader aspects of the invention to.thisspecific construction.

Referring now to Figures 2, 3 and 4, there is rotatably mounted upon thearm 33 of thev swinging'mount an element generally indicated by thenumeral 48 which is formed by bending a pieceA v I of metal to provideportions 49 having their4 ends spaced to provide a guide slot 50,adapted to receive the projection or fln formed by the members 450i thecap 40. The element 48 is rotatably mounted in an opening 5I of the armby means of a tubular extension 52, as` show n. Arranged symmetricallyon opposite sides of the slot 50 are arcuate slots corresponding inshape-'and adapted to receive elements 45 of the cap 40. Just as soon asmembers 45 enterslot 50 it is only necessary to slide the parts in onedirection or another to cause lelements 46-55 to register so thatelements 45 enter the slots or openings 55. Arm33 is slightly sprungoutwardly beforethe .parts 45 enter the slots 55, and just as soon asthese parts register the arm springs inwardly automatically. Thus a verysimple means is provided for facilitating the connection between theparts 45 and 55. The thickness ofthe fins 45 and the width of the slot5|) are so proportioned as to slide easily one inthe other. `It will ofcourse be understoodv that the s1ots'5o and ss may be in the cap 40, andthe projections 45 and 45 may be on the part 48, thus. obtaining alreversal of the parts. The means for facilitating'the Iconnection arebroadly claimed although the preferred form shown, is also claimed.There might be some advantage in making the cap- 40 l pro- The arm u hasrotatably mounted thereon a projection 58', a pin 6|' riveted to thepart 34 serving as means about' which 'this element rotates. Thiselement 68 isrounded as shown to ilt into the1 end of the tube. It isevident from an inspection of Figure 2 that if the roll were turned endfor end, that is, if the part 40 were positioned at the right instead ofat the left, no .proper connection with the support orzswing frame couldbe made. This is the ,feature which prevents wrong placement of the rollwith referenceto the'feedins mechanism and front of the cabinet. It 'mayhere be said' that any suitable mount equivalent of the arms 30--34 maybe used, it being understood thatA it is not necessary in all casesthatY there be any movement of the mount. I'he part 43 could berotatably iconnected wth the plate 35 or with the wall 31. l'Jlhefra'meis'the'pre-.u

aieaasa ferred construction because it can be swung to a point outsideof the cabinet. i

Referring now to the modification illustrated in Figures 6 to 10inclusive, the cap element is generally indicated at 56 and is connectedkby vmeans of the prongs 4|' as in case of the rst form. Referring toFigures 8 and 10, the cap or` form and which are symmetrically placedwith reference to the axis of rotation.

It is noted that the cap and its elements 59 and 60 are all of one pieceof metal made -.by

punching, and this' isla feature of all of the de-v vices herein,including the mount elements.

Referring again to Figure 8 the arm 33 has rotatablyattached thereto bymeans of a tubular extension 62 a mount element indicated at 6|. Thiselement 6I is formed by 4bending a strip of metal upon itself as shownto form a spaced out guide portion 63, which is narrower than the baseportion. The ends of the element are secured asr by spot Awelding at 64.This guide part 63 slidably fits between the parallel elements 59.Introduction by sliding motionmay be made at either end of the element6|. In this guide portion 63 are two arcuate slots 68 which positionallycorre spond to and which receive the arcuate outstanding ears or lugs 60of the cap. It will be seen that as soon as the part 63 is placed in thegroove l formed by parts 59, slight sliding motion one way or the otherwill bring parts 60 into registration with the parts 68, to enterthereinto, 'and thus connect the roll to the mount.

Referring Vnow to Figures 11 to 13 inclusive, in this form no guidingmeans to facilitate connection is used. The cap 10 is provided withprongs 4i", and with punchedout outstanding arcuate portions 1Isymmetrically arranged as shown about the axis of rotation of the wall.The arm 33 has rotatably secured thereto a mount element 15rotatably'held by means of a tubular portion 16. The element 'l5 has endportions 11 formed by bending inwardly as shown, and the ends of theseportions are so formed that they cooperate to deilne an open-end Sshaped slot 18. The shape of this slot is such as to receive and connectwith the arcuate parts 1i. The specific construction of this device is afeature of this invention.

.Referring now to Figures 14 and 15 another modification is shown inwhich the cap is provided with punched-out guide elements 60, and withoutstanding arcuate elements 8l. All elements are arranged symmetricallyasin the other cases. The connecting mount element which is attached tothe arm 33 has a structure substantially like Figure 9 with theexception` that the S shaped slot 6?. is closed. The slot is adapted toreceive the parts 6l which as viewed in Figure 15 are reversed S shaped.Again it is noted that the cap may have the slot and the mount have theprojection.-

It is further noted that in all formsof the in'- V vention with theexception of that form illustrated in Figures 12 and 14, guidemeansis-provided for facilitating the connection between the elementsrespectively of the. cap and of the mount. 4This means is thereforebroildllli claimed because I believe myself the rst to kprovide anymeans for facilitating such a connection and moreover the rst to provideany of the specific means shown herein and the first to connect a cap ina core immovably and simply and in the manner shown.

It isA again noted that the cooperative locking parts are arrangedsymmetrically about the axis ofrotation lof the roll. Just as soon asregistration is obtained between the guides, it is only necessary toslightly slide'the parts in one direction or another to cause theconnecting means to connect. In both forms the guide means'provide a.projection on one of'the elements fitting a groove in the other.

It is further noted that the projecting parts of the guide means arelonger in an axial direction than the projecting parts of the'connectingmeans, so that the slide or guide groove 'is deep enough to perform theguiding function while the outer ends of the projecting parts of saidconnecting means ride along the inner surface of the guide part of themount. l

In Figure' 16 a modification has been shown 4wherein a ring or annulusis attached to the core.

In this, as in the other forms, the attachment' is made by expanding'theprongs, to cause them 4to bite into the material of the core and thusimmovably secure the cap or ring.

Numeral generally indicates a cap having punched out diametricallyrelated arcuate attaching projections 9|. The ring 90 has inwardextensions which, normally or before attachment of the cap, occupy theposition shown in the drawings, but which arevto 'be expanded outwardlyas indicated by the arrows by a suitable. tool introduced through theopening 93 of the ring. It, of course, will be understood that when thisoccurs the prongs 96 bite into the material of the core 3i as has beenindicated in Figure 17.,

vThe advantage here is that instead of introducinga tool, or mandrel,from the opposite'end of,

the core, the expanding tool may be introduced through an opening in thering, that is, introduction is at the same end as that to which the capis attached. The cap in this instance has a spool-like relation to thematerial on the core.` 'Ifhat is. it overlaps thismaterial. Numeral 33indicates one of the arms of the swinging mount and this arm hasattached thereto an element .indicated at 98 which is the substantialequivalent of element 15, of Figure 11, and which has therein arcuateslots 91 receiving the arcuate projections 9|. The feature of this formhasin common with the feature of the other forms, the connection of thecap by expanding prongs into the material of the cover.
